FIELD OF INVENTION

This invention relates generally to the field of soybean breeding,specifically relating to a soybean variety designated XB41V13.

BACKGROUND

The present invention relates to a new and distinctive soybean varietydesignated XB41V13, which has been the result of years of carefulbreeding and selection in a comprehensive soybean breeding program.There are numerous steps in the development of any novel, desirablesoybean variety. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possess the traits to meetthe program goals. The breeder's goal is to combine in a single varietyan improved combination of desirable traits from the parental germplasm.These important traits may include, but are not limited to: higher seedyield, resistance to diseases and/or insects, tolerance to droughtand/or heat, altered fatty acid profile(s), abiotic stress tolerance,improvements in compositional traits, and better agronomiccharacteristics.

These product development processes, which lead to the final step ofmarketing and distribution, can take from six to twelve years from thetime the first cross is made until the finished seed is delivered to thefarmer for planting. Therefore, development of new varieties is atime-consuming process that requires precise planning, efficient use ofresources, and a minimum of changes in direction.

Soybean (Glycine max) is an important and valuable field crop. Thus, acontinuing goal of soybean breeders is to develop stable, high yieldingsoybean varieties that are agronomically sound. The reasons for thisgoal are to maximize the amount of grain produced on the land used andto supply food for both animals and humans. To accomplish this goal, thesoybean breeder must select and develop soybean plants that have thetraits that result in superior varieties.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated, and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic, and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report”, Iowa Soybean Promotion Board & American SoybeanAssociation Special Report 92S, May 1990). Changes in fatty acidcomposition for improved oxidative stability and nutrition are alsoimportant traits.

Industrial uses for processed soybean oil include ingredients forpaints, plastics, fibers, detergents, cosmetics, and lubricants. Soybeanoil may be split, inter-esterified, sulfurized, epoxidized, polymerized,ethoxylated, or cleaved. Designing and producing soybean oil derivativeswith improved functionality, oliochemistry, is a rapidly growing field.The typical mixture of triglycerides is usually split and separated intopure fatty acids, which are then combined with petroleum-derivedalcohols or acids, nitrogen, sulfonates, chlorine, or with fattyalcohols derived from fats and oils.

Soybean is also used as a food source for both animals and humans.Soybean is widely used as a source of protein for animal feeds forpoultry, swine, and cattle. During processing of whole soybeans, thefibrous hull is removed and the oil is extracted. The remaining soybeanmeal is a combination of carbohydrates and approximately 50% protein.

For human consumption soybean meal is made into soybean flour which isprocessed to protein concentrates used for meat extenders or specialtypet foods. Production of edible protein ingredients from soybean offersa healthy, less expensive replacement for animal protein in meats anddairy products.

DETAILED DESCRIPTION

Soybean variety XB41V13 has shown uniformity and stability for alltraits, as described in the following variety description information.Soybean variety XB41V13 was developed from a cross of RJS39003 with94Y90. Variety XB41V13 is an F3-derived line which was advanced to theF3 generation by modified single-seed descent. It has beenself-pollinated a sufficient number of generations, with carefulattention to uniformity of plant type to ensure a sufficient level ofhomozygosity and phenotypic stability. The variety has been increasedwith continued observation for uniformity. No variant traits have beenobserved or are expected.

A variety description of soybean variety XB41V13 is provided in Table 1.Traits reported are average values for all locations and years orsamples measured. Preliminary scores are reported as double digits, forexample ‘55’ indicates a preliminary score of 5 on the scale of 1 to 9.

Soybean variety XB41V13, being substantially homozygous, can bereproduced by planting seeds of the variety, growing the resultingsoybean plants under self-pollinating or sib-pollinating conditions, andharvesting the resulting seed, using techniques familiar to theagricultural arts. Development of soybean variety XB41V13 is shown inthe breeding history summary in Table 4.

Performance Examples of XB41V13

As shown in Table 2, the traits and characteristics of soybean varietyXB41V13 are given in paired comparisons with other varieties. Traitsreported are mean values for all locations and years where pairedcomparison data was obtained.

Genetic Marker Profile

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety ora related variety, or which can be used to determine or validate apedigree. Genetic marker profiles can be obtained by techniques such asrestriction fragment length polymorphisms (RFLPs), randomly amplifiedpolymorphic DNAs (RAPDs), arbitrarily primed polymerase chain reaction(AP-PCR), DNA amplification fingerprinting (DAF), sequence characterizedamplified regions (SCARs), amplified fragment length polymorphisms(AFLPs), simple sequence repeats (SSRs) also referred to asmicrosatellites, or single nucleotide polymorphisms (SNPs). For example,see Cregan et al. (1999) “An Integrated Genetic Linkage Map of theSoybean Genome” Crop Science 39:1464-1490, and Berry et al. (2003)“Assessing Probability of Ancestry Using Simple Sequence RepeatProfiles: Applications to Maize Inbred Lines and Soybean Varieties”Genetics 165:331-342, each of which are incorporated by reference hereinin their entirety.

Methods of characterizing soybean variety XB41V13, or a varietycomprising the morphological and physiological characteristics ofsoybean variety XB41V13, are provided. In one example a methodcomprising isolating nucleic acids from a plant, a plant part, or a seedof soybean variety XB41V13, analyzing said nucleic acids to producedata, and recording the data for XB41V13 is provided. In some examplesthe data comprises one of more of a nucleic acid sequence, a geneticprofile, a molecular profile, a marker profile, a haplotype, or anycombination thereof. In some examples, the data is recorded on acomputer readable medium. In other examples, the methods may furthercomprise using the data for soybean crossing, selection and/oradvancement decisions. Crossing includes any type of plant breedingcrossing method, including but not limited to outcrossing, selfing,backcrossing, locus conversion, introgression and the like.

In some examples, one or more markers are used to characterize and/orevaluate a soybean variety. Particular markers used for these purposesare not limited to any particular set of markers, but are envisioned toinclude any type of marker and marker profile which provides a means ofdistinguishing varieties. For example, one set of publicly availablemarkers which could be used to screen and identify variety XB41V13 isdisclosed in Table 3. In another example, one method of comparison is touse only homozygous loci for XB41V13.

Primers and PCR protocols for assaying these and other markers aredisclosed in Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University) located on the world wide web at129.186.26.94/SSR.html. In addition to being used for identification ofsoybean variety XB41V13, and plant parts and plant cells of varietyXB41V13, the genetic profile may be used to identify a soybean plantproduced through the use of XB41V13 or to verify a pedigree for progenyplants produced through the use of XB41V13. The genetic marker profileis also useful in breeding and developing backcross conversions.

The present invention comprises a soybean plant characterized bymolecular and physiological data obtained from the representative sampleof said variety deposited with the American Type Culture Collection(ATCC). Thus, plants, seeds, or parts thereof, having all orsubstantially all of the physiological and morphological characteristicsof soybean variety XB41V13 are provided. Further provided is a soybeanplant formed by the combination of the disclosed soybean plant or plantcell with another soybean plant or cell and comprising the homozygousalleles of the variety. A soybean plant comprising all of thephysiological and morphological characteristics of soybean varietyXB41V13 can be combined with another soybean plant in a soybean breedingprogram. In some examples the other soybean plant comprises all of thephysiological and morphological characteristics of soybean varietyXB41V13.

In some examples, a plant, a plant part, or a seed of soybean varietyXB41V13 is characterized by producing a molecular profile. A molecularprofile includes but is not limited to one or more genotypic and/orphenotypic profile(s). A genotypic profile includes but is not limitedto a marker profile, such as a genetic map, a linkage map, a traitmarker profile, a SNP profile, an SSR profile, a genome-wide markerprofile, a haplotype, and the like. A molecular profile may also be anucleic acid sequence profile, and/or a physical map. A phenotypicprofile includes but is not limited to a protein expression profile, ametabolic profile, an mRNA expression profile, and the like.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. A marker system based on SSRs can be highlyinformative in linkage analysis relative to other marker systems in thatmultiple alleles may be present. Another advantage of this type ofmarker is that, through use of flanking primers, detection of SSRs canbe achieved, for example, by using the polymerase chain reaction (PCR),thereby eliminating the need for labor-intensive Southern hybridization.PCR detection is done using two oligonucleotide primers flanking thepolymorphic segment of repetitive DNA to amplify the SSR region.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which correlates to the number of base pairsof the fragment. While variation in the primer used or in laboratoryprocedures can affect the reported fragment size, relative values shouldremain constant regardless of the specific primer or laboratory used.When comparing varieties it is preferable if all SSR profiles areperformed in the same lab.

Primers used are publicly available and may be found in Soybase orCregan (1999 Crop Science 39:1464-1490). See also, WO 99/31964“Nucleotide Polymorphisms in Soybean”, U.S. Pat. No. 6,162,967“Positional Cloning of Soybean Cyst Nematode Resistance Genes”, and U.S.Pat. No. 7,288,386 “Soybean Sudden Death Syndrome Resistant Soybeans andMethods of Breeding and Identifying Resistant Plants”, the disclosuresof which are incorporated herein by reference.

The SSR profile of soybean plant XB41V13 can be used to identify plantscomprising XB41V13 as a parent, since such plants will comprise the samehomozygous alleles as XB41V13. Because the soybean variety isessentially homozygous at all relevant loci, most loci should have onlyone type of allele present. In contrast, a genetic marker profile of anF1 progeny should be the sum of those parents, e.g., if one parent washomozygous for allele X at a particular locus, and the other parenthomozygous for allele Y at that locus, then the F1 progeny will be XY(heterozygous) at that locus. Subsequent generations of progeny producedby selection and breeding are expected to be of genotype XX(homozygous), YY (homozygous), or XY (heterozygous) for that locusposition. When the F1 plant is selfed or sibbed for successive filialgenerations, the locus should be either X or Y for that position.

In addition, plants and plant parts substantially benefiting from theuse of XB41V13 in their development, such as XB41V13 comprising abackcross conversion, transgene, or genetic sterility factor, may beidentified by having a molecular marker profile with a high percentidentity to XB41V13. Such a percent identity might be 90%, 91%, 92%,93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, or 99.9% identical to XB41V13.

The SSR profile of variety XB41V13 also can be used to identifyessentially derived varieties and other progeny varieties developed fromthe use of XB41V13, as well as cells and other plant parts thereof.Plants of the invention include any plant having at least 90%, 91%, 92%,93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, or 99.9% of the markers in theSSR profile, and that retain 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%,98%, 99%, 99.5%, or 99.9% of the physiological and morphologicalcharacteristics of variety XB41V13 when grown under the same conditions.Such plants may be developed using the markers identified in WO00/31964, U.S. Pat. No. 6,162,967 and U.S. Pat. No. 7,288,386. Progenyplants and plant parts produced using XB41V13 may be identified byhaving a molecular marker profile of at least 25%, 30%, 35%, 40%, 45%,50%, 55%, 60%, 65%, 70%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%,84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%,98%, 99% or 99.5% genetic contribution from soybean variety XB41V13, asmeasured by either percent identity or percent similarity. Such progenymay be further characterized as being within a pedigree distance ofXB41V13, such as within 1, 2, 3, 4, or 5 or less cross-pollinations to asoybean plant other than XB41V13, or a plant that has XB41V13 as aprogenitor. Unique molecular profiles may be identified with othermolecular tools such as SNPs and RFLPs.

Introduction of a New Trait or Locus into XB41V13

Variety XB41V13 represents a new base genetic variety into which a newlocus or trait may be introgressed. Direct transformation andbackcrossing represent two important methods that can be used toaccomplish such an introgression.

A backcross conversion of XB41V13 occurs when DNA sequences areintroduced through backcrossing (Hallauer et al. in Corn and CornImprovement, Sprague and Dudley, Third Ed. 1998) with XB41V13 utilizedas the recurrent parent. Both naturally occurring and transgenic DNAsequences may be introduced through backcrossing techniques. A backcrossconversion may produce a plant with a trait or locus conversion in atleast two or more backcrosses, including at least 2 backcrosses, atleast 3 backcrosses, at least 4 backcrosses, at least 5 backcrosses, ormore. Molecular marker assisted breeding or selection may be utilized toreduce the number of backcrosses necessary to achieve the backcrossconversion. For example, see Openshaw et al., “Marker-assisted Selectionin Backcross Breeding”. In: Proceedings Symposium of the Analysis ofMolecular Data, August 1994, Crop Science Society of America, Corvallis,Oreg., which demonstrated that a backcross conversion can be made in asfew as two backcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (a single gene or closely linked genes comparedto unlinked genes), the level of expression of the trait, the type ofinheritance (cytoplasmic or nuclear), dominant or recessive traitexpression, and the types of parents included in the cross. It isunderstood by those of ordinary skill in the art that for single genetraits that are relatively easy to classify, the backcross method iseffective and relatively easy to manage. (See Hallauer et al., in Cornand Corn Improvement, Sprague and Dudley, Third Ed. 1998). Desiredtraits that may be transferred through backcross conversion include, butare not limited to, sterility (nuclear and cytoplasmic), fertilityrestoration, nutritional enhancements, drought tolerance, nitrogenutilization, altered fatty acid profile, low phytate, industrialenhancements, disease resistance (bacterial, fungal, or viral), insectresistance, and herbicide resistance. In addition, a recombination siteitself, such as an FRT site, Lox site, or other site specificintegration site, may be inserted by backcrossing and utilized fordirect insertion of one or more genes of interest into a specific plantvariety. A single locus may contain several transgenes, such as atransgene for disease resistance and a transgene for herbicideresistance. The gene for herbicide resistance may be used as aselectable marker and/or as a phenotypic trait. A single locusconversion of site specific integration system allows for theintegration of multiple genes at a known recombination site in thegenome.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest can be accomplished by direct selection for atrait associated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the trait(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withsubsequent selection for the trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehlman suggests from one tofour or more backcrosses, but as noted above, the number of backcrossesnecessary can be reduced with the use of molecular markers (Poehlman etal., (1995) Breeding Field Crops, 4th Ed., Iowa State University Press,Ames, Iowa). Other factors, such as a genetically similar donor parent,may also reduce the number of backcrosses necessary. As noted byPoehlman, backcrossing is easiest for simply inherited, dominant, andeasily recognized traits.

One process for adding or modifying a trait or locus in soybean varietyXB41V13 comprises crossing XB41V13 plants grown from XB41V13 seed withplants of another soybean plant that comprises a desired trait lackingin XB41V13, selecting F1 progeny plants that possess the desired traitor locus to produce selected F1 progeny plants, crossing the selectedprogeny plants back to XB41V13 plants to produce backcross) (BC1)progeny plants. The BC1F1 progeny plants that have the desired trait andthe morphological characteristics of soybean variety XB41V13 areselected and backcrossed to XB41V13 to generate BC2F1 progeny plants.Additional backcrossing and selection of progeny plants with the desiredtrait will produce BC3F1, BC4F1, BC5F1, . . . BCxF1 generations ofplants. The backcross populations of XB41V13 may be furthercharacterized as having the physiological and morphologicalcharacteristics of soybean variety XB41V13 listed in Table 1 asdetermined at the 5% significance level when grown in the sameenvironmental conditions and/or may be characterized by percentsimilarity or identity to XB41V13 as determined by SSR or othermolecular markers. The above method may be utilized with fewerbackcrosses in appropriate situations, such as when the donor parent ishighly related or molecular markers are used in one or more selectionsteps. Desired traits that may be used include those nucleic acids knownin the art, some of which are listed herein, that will affect traitsthrough nucleic acid expression or inhibition. Desired loci also includethe introgression of FRT, Lox, and/or other recombination sites for sitespecific integration. Desired loci further include QTLs, which may alsoaffect a desired trait.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing XB41V13with the introgressed trait or locus with a different soybean plant andharvesting the resultant first generation progeny soybean seed.

Transgenes and transformation methods provide means to engineer thegenome of plants to contain and express heterologous genetic elements,including but not limited to foreign genetic elements, additional copiesof endogenous elements, and/or modified versions of native or endogenousgenetic elements, in order to alter at least one trait of a plant in aspecific manner that would be difficult or impossible to obtain withtraditional plant breeding alone. Any heterologous DNA sequence(s),whether from a different species or from the same species, which areinserted into the genome using transformation, backcrossing, or othermethods known to one of skill in the art are referred to hereincollectively as transgenes. The sequences are heterologous based onsequence source, location of integration, operably linked elements, orany combination thereof. One or more transgenes of interest can beintroduced into soybean variety XB41V13. Transgenic variants of soybeanvariety XB41V13 plants, seeds, cells, and parts thereof or derivedtherefrom are provided. Transgenic variants of XB41V13 comprise thephysiological and morphological characteristics of soybean varietyXB41V13 listed in Table 1 as determined at the 5% significance levelwhen grown in the same environmental conditions, and/or may becharacterized or identified by percent similarity or identity to XB41V13as determined by SSR or other molecular markers. In some examples,transgenic variants of soybean variety XB41V13 are produced byintroducing at least one transgene of interest into soybean varietyXB41V13 by transforming XB41V13 with a polynucleotide comprising thetransgene of interest. In other examples, transgenic variants of soybeanvariety XB41V13 are produced by introducing at least one transgene byintrogressing the transgene into soybean variety XB41V13 by crossing.

In one example, a process for modifying soybean variety XB41V13 with theaddition of a desired trait, said process comprising transforming asoybean plant of variety XB41V13 with a transgene that confers a desiredtrait is provided. Therefore, transgenic XB41V13 soybean cells, plants,plant parts, and seeds produced from this process are provided. In someexamples one more desired traits may include traits such as herbicideresistance, insect resistance, disease resistance, decreased phytate,modified fatty acid profile, modified fatty acid content, carbohydratemetabolism, protein content, or oil content. The specific gene may beany known in the art or listed herein, including but not limited to apolynucleotide conferring resistance to imidazolinone, sulfonylurea,protoporphyrinogen oxidase (PPO) inhibitors, hydroxyphenyl pyruvatedioxygenase (HPPD) inhibitors, glyphosate, glufosinate, triazine,2,4-dichlorophenoxyacetic acid (2,4-D), dicamba, broxynil, metribuzin,or benzonitrile herbicides; a polynucleotide encoding a Bacillusthuringiensis polypeptide, a polynucleotide encoding a phytase, a fattyacid desaturase (e.g., FAD-2, FAD-3), galactinol synthase, a raffinosesynthetic enzyme; or a polynucleotide conferring resistance to soybeancyst nematode, brown stem rot, Phytophthora root rot, soybean mosaicvirus, sudden death syndrome, or other plant pathogen.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88; and Armstrong (1999) “The First Decade of Maize Transformation: AReview and Future Perspective” Maydica 44:101-109. In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

The most prevalent types of plant transformation methods involve theconstruction of an expression vector. Such a vector comprises a DNAsequence that contains a gene under the control of or operatively linkedto a regulatory element, for example a promoter. The vector may containone or more genes and one or more regulatory elements.

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed soybean variety into anelite soybean variety, and the resulting backcross conversion plantwould then contain the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences.

Transgenic plants can be used to produce commercial quantities of aforeign protein. Thus, techniques for the selection and propagation oftransformed plants, which are well understood in the art, yield aplurality of transgenic plants that are harvested in a conventionalmanner, and a heterologous protein then can be extracted from a tissueof interest or from total biomass. Protein extraction from plant biomasscan be accomplished by known methods which are discussed, for example,by Heney and Orr (1981) Anal. Biochem. 114:92-6.

A genetic map can be generated that identifies the approximatechromosomal location of the integrated DNA molecule, for example viaconventional restriction fragment length polymorphisms (RFLP),polymerase chain reaction (PCR) analysis, simple sequence repeats (SSR),and single nucleotide polymorphisms (SNP). For exemplary methodologiesin this regard, see Glick and Thompson, Methods in Plant MolecularBiology and Biotechnology, pp. 269-284 (CRC Press, Boca Raton, 1993).

Wang et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome”, Science (1998)280:1077-1082, and similar capabilities are increasingly available forthe soybean genome. Map information concerning chromosomal location isuseful for proprietary protection of a subject transgenic plant. Ifunauthorized propagation is undertaken and crosses made with othergermplasm, the map of the integration region can be compared to similarmaps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons could involvehybridizations, RFLP, PCR, SSR, sequencing or combinations thereof, allof which are conventional techniques. SNPs may also be used alone or incombination with other techniques.

Likewise, plants can be genetically engineered to express variousphenotypes of agronomic interest. Through the transformation of soybeanthe expression of genes can be altered to enhance disease resistance,insect resistance, herbicide resistance, agronomic, grain quality, andother traits. Transformation can also be used to insert DNA sequenceswhich control or help control male-sterility. DNA sequences native tosoybean as well as non-native DNA sequences can be transformed intosoybean and used to alter levels of native or non-native proteins.Various promoters, targeting sequences, enhancing sequences, and otherDNA sequences can be inserted into the genome for the purpose ofaltering the expression of proteins. Reduction of the activity ofspecific genes (also known as gene silencing or gene suppression) isdesirable for several aspects of genetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to, knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook ch.118 (Springer-Verlag 1994); antisense technology (see, e.g., Sheehy etal.

Exemplary nucleotide sequences that may be altered by geneticengineering include, but are not limited to, those categorized below.

1. Transgenes that Confer Resistance to Insects or Disease and thatEncode:

(A) Plant disease resistance genes. Plant defenses are often activatedby specific interaction between the product of a disease resistance gene(R) in the plant and the product of a corresponding avirulence (Avr)gene in the pathogen. A plant variety can be transformed with clonedresistance gene to engineer plants that are resistant to specificpathogen strains. See, for example Jones et al. (1994) Science 266: 789(cloning of the tomato Cf-9 gene for resistance to Cladosporium fulvum);Martin et al. (1993) Science 262:1432 (tomato Pto gene for resistance toPseudomonas syringae pv. tomato encodes a protein kinase); Mindrinos etal. (1994) Cell 78:1089 (Arabidopsis RPS2 gene for resistance toPseudomonas syringae), McDowell & Woffenden (2003) Trends Biotechnol.21:178-83; and Toyoda et al. (2002) Transgenic Res. 11:567-82. A plantresistant to a disease is one that is more resistant to a pathogen ascompared to the wild type plant.

4. Genes that Control Male-Sterility

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al., and chromosomal translocationsas described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al. U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed. Male sterile soybean lines and characterization arediscussed in Palmer (2000) Crop Sci 40:78-83, and Jin et al. (1997) SexPlant Reprod 10:13-21.

5. Polynucleotides comprising a sequence for site specific DNArecombination. This includes the introduction of at least one FRT sitethat may be used in the FLP/FRT system and/or a Lox site that may beused in the Cre/Lox system. For example, see Lyznik et al. (2003) PlantCell Rep 21:925-932; and WO 99/25821, which are hereby incorporated byreference. Other systems that may be used include the Gin recombinase ofphage Mu (Maeser et al.

Development of Soybean Sublines

Sublines of XB41V13 may also be developed and are provided. AlthoughXB41V13 contains substantially fixed genetics and is phenotypicallyuniform with no off-types expected, there still remains a smallproportion of segregating loci either within individuals or within thepopulation as a whole. Sublining provides the ability to select forthese loci, which have no apparent morphological or phenotypic effect onthe plant characteristics, but may have an effect on overall yield. Forexample, the methods described in U.S. Pat. Nos. 5,437,697, 7,973,212,and US2011/0258733, and US2011/0283425 (each of which is hereinincorporated by reference) may be utilized by a breeder of ordinaryskill in the art to identify genetic loci that are associated with yieldpotential to further purify the variety in order to increase its yield.A breeder of ordinary skill in the art may fix agronomically importantloci by making them homozygous in order to optimize the performance ofthe variety. The development of soybean sublines and the use ofaccelerated yield technology is a plant breeding technique.

Soybean varieties such as XB41V13 are typically developed for use inseed and grain production. However, soybean varieties such as XB41V13also provide a source of breeding material that may be used to developnew soybean varieties. Plant breeding techniques known in the art andused in a soybean plant breeding program include, but are not limitedto, recurrent selection, mass selection, bulk selection, backcrossing,pedigree breeding, open pollination breeding, restriction fragmentlength polymorphism enhanced selection, genetic marker enhancedselection, making double haploids, and transformation. Oftencombinations of these techniques are used. The development of soybeanvarieties in a plant breeding program requires, in general, thedevelopment and evaluation of homozygous varieties. There are manyanalytical methods available to evaluate a new variety. The oldest andmost traditional method of analysis is the observation of phenotypictraits but genotypic analysis may also be used.

Methods for producing a soybean plant by crossing a first parent soybeanplant with a second parent soybean plant wherein the first and/or secondparent soybean plant is variety XB41V13 are provided. Also provided aremethods for producing a soybean plant having substantially all of themorphological and physiological characteristics of variety XB41V13, bycrossing a first parent soybean plant with a second parent soybean plantwherein the first and/or the second parent soybean plant is a planthaving substantially all of the morphological and physiologicalcharacteristics of variety XB41V13 set forth in Table 1, as determinedat the 5% significance level when grown in the same environmentalconditions. The other parent may be any soybean plant, such as a soybeanplant that is part of a synthetic or natural population. Any suchmethods using soybean variety XB41V13 include but are not limited toselfing, sibbing, backcrossing, mass selection, pedigree breeding, bulkselection, hybrid production, crossing to populations, and the like.These methods are well known in the art and some of the more commonlyused breeding methods are described below. Descriptions of breedingmethods can be found in one of several reference books (e.g., Allard,Principles of Plant Breeding, 1960; Simmonds, Principles of CropImprovement, 1979; Fehr, “Breeding Methods for Cultivar Development”,Chapter 7, Soybean Improvement, Production and Uses, 2^(nd) ed., Wilcoxeditor, 1987).

Pedigree breeding starts with the crossing of two genotypes, such asXB41V13 or a soybean variety having all of the morphological andphysiological characteristics of XB41V13, and another soybean varietyhaving one or more desirable characteristics that is lacking or whichcomplements XB41V13. If the two original parents do not provide all thedesired characteristics, other sources can be included in the breedingpopulation. In the pedigree method, superior plants are selfed andselected in successive filial generations. In the succeeding filialgenerations, the heterozygous allele condition gives way to thehomozygous allele condition as a result of inbreeding. Typically in thepedigree method of breeding, five or more successive filial generationsof selfing and selection are practiced: e.g., F1→F2; F2→F3; F3→F4;F4→F5; etc. In some examples, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or moregenerations of selfing and selection are practiced. After a sufficientamount of inbreeding, successive filial generations will serve toincrease seed of the developed variety. Typically, the developed varietycomprises homozygous alleles at about 95% or more of its loci.

In addition to being used to create backcross conversion populations,backcrossing can also be used in combination with pedigree breeding. Asdiscussed previously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety (the donor parent) to adeveloped variety (the recurrent parent), which has good overallagronomic characteristics yet may lack one or more other desirabletraits. However, the same procedure can be used to move the progenytoward the genotype of the recurrent parent but at the same time retainmany components of the non-recurrent parent by stopping the backcrossingat an early stage and proceeding with selfing and selection. Forexample, a soybean variety may be crossed with another variety toproduce a first generation progeny plant. The first generation progenyplant may then be backcrossed to one of its parent varieties to create aBC1F1. Progeny are selfed and selected so that the newly developedvariety has many of the attributes of the recurrent parent and yetseveral of the desired attributes of the donor parent. This approachleverages the value and strengths of both parents for use in new soybeanvarieties.

Therefore, in some examples a method of making a backcross conversion ofsoybean variety XB41V13, comprising the steps of crossing a plant ofsoybean variety XB41V13 or a soybean variety having all of themorphological and physiological characteristics of XB41V13 with a donorplant possessing a desired trait to introduce the desired trait,selecting an F1 progeny plant containing the desired trait, andbackcrossing the selected F1 progeny plant to a plant of soybean varietyXB41V13 are provided. This method may further comprise the step ofobtaining a molecular marker profile of soybean variety XB41V13 andusing the molecular marker profile to select for a progeny plant withthe desired trait and the molecular marker profile of XB41V13. Themolecular marker profile can comprise information from one or moremarkers. In one example the desired trait is a mutant gene or transgenepresent in the donor parent. In another example, the desired trait is anative trait in the donor parent.

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. Variety XB41V13, and/or a soybeanvariety having all of the morphological and physiologicalcharacteristics of XB41V13, is suitable for use in a recurrent selectionprogram. The method entails individual plants cross pollinating witheach other to form progeny. The progeny are grown and the superiorprogeny selected by any number of selection methods, which includeindividual plant, half-sib progeny, full-sib progeny, and selfedprogeny. The selected progeny are cross pollinated with each other toform progeny for another population. This population is planted and,again, superior plants are selected to cross pollinate with each other.Recurrent selection is a cyclical process and therefore can be repeatedas many times as desired. The objective of recurrent selection is toimprove the traits of a population. The improved population can then beused as a source of breeding material to obtain new varieties forcommercial or breeding use, including the production of a syntheticcultivar. A synthetic cultivar is the resultant progeny formed by theintercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection, seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk, andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self pollination, directed pollinationcould be used as part of the breeding program.

Mutation breeding is another method of introducing new traits intosoybean variety XB41V13 or a soybean variety having all of themorphological and physiological characteristics of XB41V13. Mutationsthat occur spontaneously or that are artificially induced can be usefulsources of variability for a plant breeder. The goal of artificialmutagenesis is to increase the rate of mutation for a desiredcharacteristic. Mutation rates can be increased by many different meansincluding temperature, long-term seed storage, tissue cultureconditions, radiation; such as X-rays, gamma rays (e.g., cobalt 60 orcesium 137), neutrons, (product of nuclear fission by uranium 235 in anatomic reactor), beta radiation (emitted from radioisotopes such asphosphorus 32 or carbon 14), ultraviolet radiation (preferably from 2500to 2900 nm), or chemical mutagens such as base analogues(5-bromo-uracil), related compounds (8-ethoxy caffeine), antibiotics(streptonigrin), alkylating agents (sulfur mustards, nitrogen mustards,epoxides, ethylenamines, sulfates, sulfonates, sulfones, lactones),azide, hydroxylamine, nitrous acid, or acridines. Once a desired traitis observed through mutagenesis, the trait may then be incorporated intoexisting germplasm by traditional breeding techniques. Details ofmutation breeding can be found in “Principles of Cultivar Development”Fehr, 1993, Macmillan Publishing Company. In addition, mutations createdin other soybean plants may be used to produce a backcross conversion ofXB41V13 that comprises such mutation.

Molecular markers, which include markers identified through the use oftechniques such as isozyme electrophoresis, restriction fragment lengthpolymorphisms (RFLPs), randomly amplified polymorphic DNAs (RAPDs),arbitrarily primed polymerase chain reaction (AP-PCR), DNA amplificationfingerprinting (DAF), sequence characterized amplified regions (SCARs),amplified fragment length polymorphisms (AFLPs), simple sequence repeats(SSRs), and single nucleotide polymorphisms (SNPs), may be used in plantbreeding methods utilizing XB41V13.

Isozyme electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker and Olsen (“Molecular Linkage Map ofSoybean (Glycine max L. Merr.)”, p. 6.131-6.138. In S. J. O'Brien (ed.)Genetic Maps: Locus Maps of Complex Genomes. (1993) Cold Spring HarborLaboratory Press. Cold Spring Harbor, N.Y.), developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD (random amplified polymorphic DNA), three classicalmarkers, and four isozyme loci. See also, Shoemaker “RFLP Map ofSoybean”. pp 299-309 (1994). In R. L. Phillips and I. K. Vasil (ed.)DNA-based markers in plants. Kluwer Academic Press Dordrecht, theNetherlands.

SSR technology is an efficient and practical marker technology; moremarker loci can be routinely used and more alleles per marker locus canbe found using SSRs in comparison to RFLPs. For example, Diwan andCregan, described highly polymorphic microsatellite loci in soybean withas many as 26 alleles. (Diwan and Cregan (1997) Theor. Appl. Genet.95:220-225). Single nucleotide polymorphisms (SNPs) may also be used toidentify the unique genetic composition of the XB41V13 and progenyvarieties retaining or derived from that unique genetic composition.Various molecular marker techniques may be used in combination toenhance overall resolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan et al. (1999) Crop Science 39:1464-1490. Sequences and PCRconditions of SSR loci in soybean, as well as the most current geneticmap, may be found in Soybase on the world wide web.

One use of molecular markers is quantitative trait loci (QTL) mapping.QTL mapping is the use of markers which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plantgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which variety XB41V13 or a soybean varietyhaving all of the morphological and physiological characteristics ofXB41V13 is a parent can be used to produce double haploid plants. Doublehaploids are produced by the doubling of a set of chromosomes (1 N) froma heterozygous plant to produce a completely homozygous individual. Forexample, see Wan et al., “Efficient Production of Doubled Haploid PlantsThrough Colchicine Treatment of Anther-Derived Maize Callus” (1989)Theor Appl Genet. 77:889-892, and US2003/0005479. This can beadvantageous because the process omits the generations of selfing neededto obtain a homozygous plant from a heterozygous source.

Methods for obtaining haploid plants are disclosed in Kobayashi et al.(1980) J Heredity 71:9-14; Pollacsek (1992) Agronomie (Paris)12:247-251; Cho-Un-Haing et al. (1996) J Plant Biol. 39:185-188;Verdoodt et al. (1998) Theor Appl Genet. 96:294-300; GeneticManipulation in Plant Breeding, Proceedings International SymposiumOrganized by EUCARPIA, Sep. 8-13, 1985, Berlin, Germany; Chalyk et al.(1994) Maize Genet Coop. Newsletter 68:47. Double haploid technology insoybean is discussed in Croser et al. (2006) Crit. Rev Plant Sci25:139-157; and Rodrigues et al. (2006) Brazilian Arc Biol Tech49:537-545.

In some examples a process for making a substantially homozygous XB41V13progeny plant by producing or obtaining a seed from the cross of XB41V13and another soybean plant and applying double haploid methods to the F1seed or F1 plant or to any successive filial generation is provided.Based on studies in maize, and currently being conducted in soybean,such methods would decrease the number of generations required toproduce a variety with similar genetics or characteristics to XB41V13.See Bernardo and Kahler (2001) Theor. Appl. Genet. 102:986-992.

In particular, a process of making seed retaining the molecular markerprofile of soybean variety XB41V13 is contemplated, such processcomprising obtaining or producing F1 seed for which soybean varietyXB41V13 is a parent, inducing doubled haploids to create progeny withoutthe occurrence of meiotic segregation, obtaining the molecular markerprofile of soybean variety XB41V13, and selecting progeny that retainthe molecular marker profile of XB41V13.

Methods using seeds, plants, cells, or plant parts of variety XB41V13 intissue culture are provided, as are the cultures, plants, parts, cells,and/or seeds derived therefrom. Tissue culture of various tissues ofsoybeans and regeneration of plants therefrom is well known and widelypublished. For example, see Komatsuda et al. (1991) Crop Sci.31:333-337; Stephens et al. “Agronomic Evaluation ofTissue-Culture-Derived Soybean Plants” (1991) Theor. Appl. Genet.82:633-635; Komatsuda et al. “Maturation and Germination of SomaticEmbryos as Affected by Sucrose and Plant Growth Regulators in SoybeansGlycine gracilis Skvortz and Glycine max (L.) Merr.” (1992) Plant CellTissue and Organ Culture 28:103-113; Dhir et al. “Regeneration ofFertile Plants from Protoplasts of Soybean (Glycine max L. Merr.):Genotypic Differences in Culture Response” (1992) Plant Cell Reports11:285-289; Pandey et al. “Plant Regeneration from Leaf and HypocotylExplants of Glycine wightii (W. and A.) VERDC. var. longicauda” (1992)Japan J. Breed. 42:1-5; and Shetty et al. “Stimulation of In Vitro ShootOrganogenesis in Glycine max (Merrill.) by Allantoin and Amides” (1992)Plant Science 81:245-251; U.S. Pat. No. 5,024,944, to Collins et al.;and U.S. Pat. No. 5,008,200, to Ranch et al., the disclosures of whichare hereby incorporated herein in their entirety by reference. Thus,another aspect is to provide cells which upon growth and differentiationproduce soybean plants having the physiological and morphologicalcharacteristics of soybean variety XB41V13.

Soybean seeds, plants, and plant parts of variety XB41V13 may be cleanedand/or treated. The resulting seeds, plants, or plant parts produced bythe cleaning and/or treating process(es) may exhibit enhanced yieldcharacteristics. Enhanced yield characteristics can include one or moreof the following: increased germination efficiency under normal and/orstress conditions, improved plant physiology, growth and/or development,such as water use efficiency, water retention efficiency, improvednitrogen use, enhanced carbon assimilation, improved photosynthesis, andaccelerated maturation, and improved disease and/or pathogen tolerance.Yield characteristics can furthermore include enhanced plantarchitecture (under stress and non-stress conditions), including but notlimited to early flowering, flowering control for hybrid seedproduction, seedling vigor, plant size, internode number and distance,root growth, seed size, fruit size, pod size, pod or ear number, seednumber per pod or ear, seed mass, enhanced seed filling, reduced seeddispersal, reduced pod dehiscence and lodging resistance. Further yieldcharacteristics include seed composition, such as carbohydrate content,protein content, oil content and composition, nutritional value,reduction in anti-nutritional compounds, improved processibility, andbetter storage stability.

Cleaning a seed or seed cleaning refers to the removal of impurities anddebris material from the harvested seed. Material to be removed from theseed includes but is not limited to soil, and plant waste, pebbles, weedseeds, broken soybean seeds, fungi, bacteria, insect material, includinginsect eggs, larvae, and parts thereof, and any other pests that existwith the harvested crop. The terms cleaning a seed or seed cleaning alsorefer to the removal of any debris or low quality, infested, or infectedseeds and seeds of different species that are foreign to the sample.

Treating a seed or applying a treatment to a seed refers to theapplication of a composition to a seed as a coating or otherwise. Thecomposition may be applied to the seed in a seed treatment at any timefrom harvesting of the seed to sowing of the seed. The composition maybe applied using methods including but not limited to mixing in acontainer, mechanical application, tumbling, spraying, misting, andimmersion. Thus, the composition may be applied as a powder, acrystalline, a ready-to-use, a slurry, a mist, and/or a soak. For ageneral discussion of techniques used to apply fungicides to seeds, see“Seed Treatment,” 2d ed., (1986), edited by K. A Jeffs (chapter 9),herein incorporated by reference in its entirety. The composition to beused as a seed treatment can comprise one or more of a pesticide, afungicide, an insecticide, a nematicide, an antimicrobial, an inoculant,a growth promoter, a polymer, a flow agent, a coating, or anycombination thereof. General classes or family of seed treatment agentsinclude triazoles, anilides, pyrazoles, carboxamides, succinatedehydrogenase inhibitors (SDHI), triazolinthiones, strobilurins, amides,and anthranilic diamides. In some examples, the seed treatment comprisestrifloxystrobin, azoxystrobin, metalaxyl, metalaxyl-m, mefenoxam,fludioxinil, imidacloprid, thiamethoxam, thiabendazole, ipconazole,penflufen, sedaxane, prothioconazole, picoxystrobin, penthiopyrad,pyraclastrobin, xemium, Rhizobia spp., Bradyrhizobium spp. (e.g., B.japonicum), Bacillus spp. (e.g., B. firmus, B. pumilus, B. subtilis),lipo-chitooligosaccharide, clothianidin, cyazapyr, rynaxapyr, abamectin,and any combination thereof. In some examples the seed treatmentcomprises trifloxystrobin, metalaxyl, imidacloprid, Bacillus spp., andany combination thereof. In some examples the seed treatment comprisespicoxystrobin, penthiopyrad, cyazapyr, ranaxapyr, and any combinationthereof. In some examples, the seed treatment improves seed germinationunder normal and/or stress environments, early stand count, vigor,yield, root formation, nodulation, and any combination thereof. In someexamples seed treatment reduces seed dust levels, insect damage,pathogen establishment and/or damage, plant virus infection and/ordamage, and any combination thereof.

Soybean seeds, plants, and plant parts of variety XB41V13 may be used orprocessed for food, animal feed, or a raw material(s) for industry.Seeds from variety XB41V13 can be crushed, or a component of the seedscan be extracted in order to make a plant product, such as proteinconcentrate, protein isolate, soybean hulls, meal, flour, or oil for afood or feed product. Methods of producing a plant product, such asprotein concentrate, protein isolate, soybean hulls, meal, flour, or oilfor a food or feed product are provided. Also provided are the proteinconcentrate, protein isolate, soybean hulls, meal, flour, or oilproduced by the methods.

Oil extracted from soybeans is used for cooking oil, margarine, andsalad dressings. Soybean oil has a typical composition of 11% palmitic,4% stearic, 25% oleic, 50% linoleic, and 9% linolenic fatty acidcontent. Industrial uses of soybean oil, which is typically subjected tofurther processing, include ingredients for paints, plastics, fibers,detergents, cosmetics, lubricants, and biodiesel fuel. Soybean oil maybe split, inter-esterified, sulfurized, epoxidized, polymerized,ethoxylated, or cleaved. To produce oil, the harvested soybeans arecracked, adjusted for moisture content, rolled into flakes, and then theoil is solvent-extracted. The oil extract is refined, optionally blendedand/or hydrogenated. Some soybean varieties have modified fatty acidprofiles and can be used to produce soybean oil with a modified fattyacid composition. Oil with 3% or less linolenic acid is classified aslow linolenic oil, oil with less than 1% linolenic acid is classified asultra low linolenic oil. Oil with 70% or higher of oleic acid isclassified as high oleic oil.

Soybeans are also used as a food source for both animals and humans.Soybeans are widely used as a source of protein for animal feed. Thefibrous hull is removed from whole soybean and the oil is extracted. Theremaining meal is a combination of carbohydrates and approximately 50%protein. This remaining meal is heat treated under well-establishedconditions and ground in a hammer mill. Soybean is a predominant sourcefor livestock feed components.

In addition to soybean meal, soybean can be used to produce soy flour.Soy flour refers to defatted soybeans where special care was takenduring desolventizing to minimize protein denaturation and to retain ahigh nitrogen solubility index (NSI) in making the flour. Soy flour isthe typical starting material for production of soy concentrate and soyprotein isolate. Defatted soy flour is obtained from solvent extractedflakes, and contains less than 1% oil. Full-fat soy flour is made fromwhole beans and contains about 18% to 20% oil. Low-fat soy flour is madeby adding back some oil to defatted soy flour. The lipid content varies,but is usually between 4.5-9%. High-fat soy flour can also be producedby adding soybean oil to defatted flour at the level of 15%.Lecithinated soy flour is made by adding soybean lecithin to defatted,low-fat or high-fat soy flours to increase dispersibility and impartemulsifying properties.

For human consumption, soybean can be used to produce edible ingredientswhich serve as an alternative source of dietary protein. Common examplesinclude milk, cheese, and meat substitutes. Additionally, soybean can beused to produce various types of fillers for meat and poultry products.Vitamins and/or minerals may be added to make soy products nutritionallymore equivalent to animal protein sources as the protein quality isalready roughly equivalent.

All publications, patents, and patent applications mentioned in thespecification are indicative of the level of those skilled in the art towhich this invention pertains. All such publications, patents, andpatent applications are incorporated by reference herein for the purposecited to the same extent as if each was specifically and individuallyindicated to be incorporated by reference herein.

The foregoing invention has been described in detail by way ofillustration and example for purposes of clarity and understanding. Asis readily apparent to one skilled in the art, the foregoing are onlysome of the methods and compositions that illustrate the embodiments ofthe foregoing invention. It will be apparent to those of ordinary skillin the art that variations, changes, modifications, and alterations maybe applied to the compositions and/or methods described herein withoutdeparting from the true spirit, concept, and scope of the invention.

As used herein, the terms “comprises,” “comprising,” “includes,”“including,” “has,” “having,” “contains”, “containing,” “characterizedby” or any other variation thereof, are intended to cover anon-exclusive inclusion. For example, a composition, mixture, process,method, article, or apparatus that comprises a list of elements is notnecessarily limited to only those elements but may include otherelements not expressly listed or inherent to such composition, mixture,process, method, article, or apparatus. The transitional phrase“consisting of” excludes any element, step, or ingredient other thanthose recited except for impurities ordinarily associated therewith.When the phrase “consisting of” appears in a clause of the body of aclaim, rather than immediately following the preamble, it limits onlythe element set forth in that clause; other elements are not excludedfrom the claim as a whole. The transitional phrase “consistingessentially of” is used to define a composition, method or apparatusthat includes materials, steps, features, components, or elements, inaddition to those literally disclosed, provided that these additionalmaterials, steps, features, components, or elements do not materiallyaffect the basic characteristic(s).

Unless expressly stated to the contrary, “or” is used as an inclusiveterm. For example, a condition A or B is satisfied by any one of thefollowing: A is true (or present) and B is false (or not present), A isfalse (or not present) and B is true (or present), and both A and B aretrue (or present).
